Improving the Precision of Three Height Estimates
Canadian Journal of Forest Research
National Research Council Canada
Two models for estimating tree height using a hypsometer, termed the two-step and one-step models, are computer simulated to determine the precision of estimates as a function of the model and the observer's viewing position about the tree. Rules of thumb guiding model selection and viewing position are formulated.
